Our hosting provider will be moving our main server onto a new processor today, which will result in far greater performance.
There will be some downtime as I will likely be not available to setup everything immediately, expect downtime of up to 16 hours. If main server is down, only fallback server can be accessed, so it'll be unplayable. For future I am slowly working towards easier manageable structure which will not require absolute main server uptime.
EDIT: It is being later than announced, so it may happen at September 14th instead
EDIT 2: maybe September 15? or 16? wow they're being really late on their word.
It has been done at September 16th night, we had exactly 9 hours of downtime
